Global Variants of Hartogs' Theorem
[OWP201824] (Mathematisches Forschungsinstitut Oberwolfach, 20181106)Hartogs' theorem asserts that a separately holomorphic function, defined on an open subset of $\mathbb{C}^n$, is holomorphic in all the variables. We prove a global variant of this theorem for functions defined on an open ... 
Gradient Canyons, Concentration of Curvature, and Lipschitz Invariants
[OWP201735] (Mathematisches Forschungsinstitut Oberwolfach, 20171213)We find new biLipschitz invariants of holomorphic functions of two variables by using the gradient canyons and by combining analytic and geometric viewpoints on the concentration of curvature. 
Graphical constructions for the sl(3), C2 and G2 invariants for virtual knots, virtual braids and free knots
[OWP201513] (Mathematisches Forschungsinstitut Oberwolfach, 20150731)We construct graphvalued analogues of the Kuperberg sl(3) and $G_2$ invariants for virtual knots. The restriction of the sl(3) and $G_2$ invariants for classical knots coincides with the usual Homflypt sl(3) invariant and ... 
A graphical interface for the GromovWitten theory of curves
[OWP201606] (Mathematisches Forschungsinstitut Oberwolfach, 20160510)We explore the explicit relationship between the descendant Gromov–Witten theory of target curves, operators on Fock spaces, and tropical curve counting. We prove a classical/tropical correspondence theorem for descendant ... 
Grassmannian connection between three and fourqubit observables, mermin's contextualities and black holes
[OWP201317] (Mathematisches Forschungsinstitut Oberwolfach, 20130723)We invoke some ideas from finite geometry to map bijectively 135 heptads of mutually commuting threequbit observables into 135 symmetric fourqubit ones. After labeling the elements of the former set in terms of a ... 
"Green Brochure" 1984
(Gesellschaft für Mathematische Forschung, 1984)Information on the Work, Organization, and History of the Mathematical Research Institute Oberwolfach on the Occasion of its Anniversary 1984. Publ. by Gesellschaft für mathematische Forschung e.V., in cooperation with ... 
Group Algebras of Compact Groups. A New Way of Producing Group Hopf Algebras over Real and Complex Fields: Weakly Complete Topological Vector Spaces
[OWP201906] (Mathematisches Forschungsinstitut Oberwolfach, 20190227)Weakly complete real or complex associative algebras $A$ are necessarily projective limits of finite dimensional algebras. Their group of units $A^{1}$ is a proLie group with the associated topological Lie algebra $A_{\rm ...

Hecke duality relations of Jacobi forms
[OWP200803] (Mathematisches Forschungsinstitut Oberwolfach, 20080307)In this paper we introduce a new subspace of Jacobi forms of higher degree via certain relations among Fourier coefficients. We prove that this space can also be characterized by duality properties of certain distinguished ... 
HeisenbergWeyl algebra revisited: combinatorics of words and paths
[OWP200902] (Mathematisches Forschungsinstitut Oberwolfach, 2009)The Heisenberg–Weyl algebra, which underlies virtually all physical representations of Quantum Theory, is considered from the combinatorial point of view. We provide a concrete model of the algebra in terms of paths on a ... 
Hemodynamical Flows : Modeling, Analysis and Simulation
[OWS37] (Birkhäuser Basel, 2008)This volume consists of six contributions concerning mathematical tools and analysis for the blood flow in arteries and veins. … book will be handy for those who are interested in the description of the flows of fluids ... 
Herbrand’s Theorem as Higher Order Recursion
[OWP201801] (Mathematisches Forschungsinstitut Oberwolfach, 20180219)We provide a means to compute Herbrand disjunctions directly from sequent calculus proofs with cuts. Our approach associates to a firstorder classical proof $\pi \vdash \exists v F$, where $F$ is quantifier free, an ... 
Hermann Weyl's Raum  Zeit  Materie and a general introduction to his scientific work
[OWS30] (Birkhäuser Basel, 2001)Historical interest and studies of Weyl's role in the interplay between 20thcentury mathematics, physics and philosophy have been increasing since the middle 1980s, triggered by different activities at the occasion of the ... 
High performance computing on smartphones
[SNAP2016006EN] (Mathematisches Forschungsinstitut Oberwolfach, 2016)Nowadays there is a strong demand to simulate even realworld engineering problems on small computing devices with very limited capacity, such as a smartphone. We explain, using a concrete example, how we can obtain a ... 
Higher Finiteness Properties of Reductive Arithmetic Groups in Positive Characteristic: the Rank Theorem
[OWP201105] (Mathematisches Forschungsinstitut Oberwolfach, 2011058)We show that the finiteness length of an $S$arithmetic subgroup $\Gamma$ in a noncommutative isotropic absolutely almost simple group $\mathcal{G}$ over a global function field is one less than the sum of the local ranks ... 
Hight functions on quaternionic Stiefel manifolds
[OWP201510] (Mathematisches Forschungsinstitut Oberwolfach, 20150729)In this note, we study height functions on quaternionic Stiefel manifolds and prove that all these height functions are MorseBott. Among them, we characterize the Morse functions and give a lower bound for their number ... 
Holomorphic automorphic forms and cohomology
[OWP201407] (Mathematisches Forschungsinstitut Oberwolfach, 20140425)We investigate the correspondence between holomorphic automorphic forms on the upper halfplane with complex weight and parabolic cocycles. For integral weights at least 2 this correspondence is given by the Eichler integral. ... 
Holonomy Groups of $G_2^*$Manifolds
[OWP201707] (Mathematisches Forschungsinstitut Oberwolfach, 20170307)We classify the holonomy algebras of manifolds admitting an indecomposable torsion free $G_2^*$structure, i.e. for which the holonomy representation does not leave invariant any proper nondegenerate subspace. We realize ...
